This invention relates to portablefitoilets for children. a a

An object of the invention is -to provide a i portable structure, more especially designed for use in connection 1 with automobiles, and l of such character that, under ordinary con-I ditions,the structure maybe usedas-a spare seat,fand when occasion arises may be used' by children as a toilet.

' Another object of the inventionis to ,proa -vide .a structure of this character, including;

a receptacle which is ordinarily concealed from view, and which is rigidly, but. detach-V ably, maintained in position, and-made readily accessible by lifting a hingedcover.

Still another object f the invention is to 1 provide,

a structureof this character, a re ceptacle which-may besealed, together with means' for introducing liquid into-the receptacle to facilitate cleaningthereof. Other and further objects and advantages? F of the invention will morefully-and clearly V -tionto be used .as aspare seat, Figure 211s a; perspective view of the structure, showing appear'from the description and claims here-1 inafterfollowing.

As shown in the drawings, the structure comprises a front wall 10,"sid'e walls" 11 and 12, and rear wall 13, all of saidwalls being formed of sheet metal, and bent to provide a rectangular 1 formation 1 tapering irom the bottomwupwardly' Each of said walls is cut out, as indicated at 14, to provide supporting feet Iii-15, one atea chcorner orthe "structure. 1 The upper-edges 'of the walls "10,

11, '12 .and13, arebent overito. provide inturned annular flanges, :16, 17' 18 and .19, and

upon-theseflanges is secured a seat portion 20, by means ofQsui'table bolts, said seat POI-1 'tion being provided withga'n annular central- 1y disposed aperture 21; 1Hinged=tovthe rear edgeof,said portion20 is-acover ori-aiuxiliary seat22, suitable hinges being indicated at;2 3.

The cover 22 is provided with a cushion on its" outer surface,

locking the cover 22 in eclosed gposition, said slots 25 -25 ,in'thecover portion 20, the lower a a ends'of thera-rms being providedwithsuitable forming a part of this; specification, Figure 1 is a perspective-view of the structure, showing the same in condi 10 Of'ithBStI'LICtIHG, said bolt being provided V 7 =with a lateralex-tension 30;a 'dapted to project for the purpose of removing or inserting the same, with respect to. the-structure; Fig. 4 is v with a shoulder 32 inthe keeper, after the olt 29has'been inserted and rotatedzto cause such engagement. v V 1 a,

Inthelower endof thestructure is mount- 7 ed a sheet metal; tank, indicated at :33, said i,

"tank being held in positio'n by suitable brackets 34-r'3 4, the upper wall 3510f the tankv serving tofdefine-the bottom ofthe compartment in @the Y structure in V which the 7 ,receptac'le 36 is disposed, the. remaining walls ,of'the compartment :per portions of :the walls 10, 11 and12 and ,the-seatf20a Y an enlargedidetail view ofa cover "forthei' provided with a suitable ",handle 37. V The being defined by'the up.

The receptacle is ofa character which maybe obtained in the 'open 'marketr A lid 360 is provided for the receptacle, which has a deep annular flange 36l'which fit's into the receptacle and substantially seals the same when the lid is in position, said lid having the user, a handle 362 being provided which lies substantially flush with the remaining body portion of the lid 360. Means 'are pro 1 vided for maintaining therecepta cle 36 in front wall 10, a sheet metal bracket 40, 'se-' position, said means including a sheet metal bracket 39 secured to the flange 17' on the cured to the flange 16 on the'walli 11 and a sheet metal bracket '41, secured to the flange 18 on the wall 12, said-bracketsbeing spaced somedistance from the under surface of the seat 20. The flange 38 of the receptacle 36'is slid between the brackets 39, 40iand-41 and the under surface of the seat 20, a fabric pad '42 being secured to .the under surface of the seat 20 and bearing upon the top of theflan'ge 38, when the receptacle 36 is imposition. The" receptacle 36'is adapted to be inserted and removed from the structure byway of a hinged door ,43' at the rear of the structure; The rear wa-ll13 is provided with an opening 44, through which the receptacle 36; is inserted or'removed, said opening being closed by'the '1 door 43. The door 43 "is providedzwith a' spring latchf45 normally urged outwardly by a spring 46, said latch being adapted to enter a recess 47 inlthe seat'20, as best. shown in Fig.

6 and Fig. 10, said latch being adapted tobe T retracted bva handle148, which depresses the latch so thatthe do ormaybe opened, the door being automatically locked-'whenthe same'is swung to closed position. 1 Theinner surface of the door isprovidedwith a rack 49, having side, frontfandbottom- -walls de fininga-pocket 50 for a plurality of sheets of 45 paper, indicated at 51. SecuredtO the for- "ward wall of the pocket 50 is a pair of spring arms 52'52, the free extremities of which are adapted to bear upon the receptacle 36, as

- best shown in Figs4and 6, the spring arms being connected together at their-inner ends by means of a connecting portion 53, the latter being secured as by welding to the front Wall 3 of the pocket 50. a Means areprovided for introducing-liquid '55 intothereceptacle 36, saidmeans including a tube 54 having its upper'endmounted'in the seat portion 20', while the lowerend'thereofextends downwardly thr'ough the nipple; p I 55 in the top wall 35 0f thetank 33, andthe' 1 I56 atthe bottomof the tank,thef lower" end of -the tube being 57, to admit the liquid from the mainbody' portion of the-tank"33. 'A noz zle or spout lower end of the tube 54isdisposed in a well provided with inletfopenings 57 is provided adjacent theupper'end'o'f the I compartment in the tube 54, which is so disposed as to conduct water from the tube 54 into the receptacle 36.

Mounted in the tube or cylinder 54 is a piston head 58 which is provided with an inlet opening 59, closed by ball valve 60. The piston head 58 is operated by a piston rod 61 extending, at its upper end, through a bushing62, and terminating in an operating hana depression to accommodate the fingersot dle 61:A, by manipulation of which the piston rod may be reciprocated to raise the liquid in the cylinder 54 and discharge the same into the receptacle 36. The tank35 is provided witha fillertube 63, having 1tsupper end mounted;.-in:the seat portion 20, a' detachable filler cap 64 being provided'to permit'filling of the'tank.

Bythe above described arrangement it will beappreciatedthat a convenient port-. able toilet is provided especially adapted for l the 7 use of children, and in' connection with automobiles, the" structure being of such character than-under ordinaryconditions,'it i may be used as a spare seat. Whenintended foruse as a toilet, the cover 22; may be raised 7 :and thelid 360 removed. Liquid maybe in-v jected into the' receptacle before and after use as desired. 'When the lid 360 is replaced the-receptacle is sealed, the cover 22 lowered and lockediin Position, so that the deviceis 1 again utilizable as aspare seat. Thelrecep} tacle is maintained against vibration or dis structure, through the rear door 43, being detachable and engageable with the holding meansby movement in opposite directions through the door opening,'the brackets 39,

40 and: '41 being so arranged as to permit this a movement, and when the receptacle is in'its structure/the spring fingers 52-52 on the door bear thereon andaid in maintaining the receptacle in proper position;. f 7 7 While we haveherein shownand described what we nowconsider the proper manner of carryingout ourfinv'ention, the same is mere 1y illustrative, changes and modifications that come within 'the 'scope of the appended hereto.
